OPTIMIZED ALLOCATION AND SCHEDULING OF RENEWABLE ENERGY IN MULTI-ENERGY COMPLEMENTARY SYSTEM AT TOWNSHIP LEVEL
On the basis of the economic optimization analysis of the renewable energy multi-energy complementary system based on biomass energy
an optimization and improvement of the power grid supplement and local consumption models were carried out using LINGO to investigate their impact on system configuration
scheduling
and economy. The results indicate that with the grid replenishment period restricted upon local consumption
the relative installed capacity proportion of wind and solar power in the system rises by 27.16 percentage points
and that of the biomass utilization unit drops by 23.09 percentage points. During the first peak and trough periods of electricity consumption
the aforementioned scheme prioritizes the use of wind power generation to reduce impacts on the power grid. During the second trough period
there is a surplus of wind and solar energy
with a priority for surplus electricity to be used for storage. Additionally
approximately 15% is consumed locally. During the second peak period
photovoltaic generation is the primary focus
with biomass energy and batteries providing assistance
and any shortfall is supplemented by the power grid. Compared to only introducing local consumption
the system the annual operating cost of the system is reduced by 32.5%
carbon emissions are reduced by 39.1%
and the investment recovery period is reduced from 8.29 a to 7.38 a.
